why temp/cm track over opk?

Temping allows you to see exactly what day you ovulate, whereas OPKs just give you an indication that you should ovulate at some point in the near future. I never bothered with CM. Temping is the clearest way to go. And once you have the thermometer, no additional costs, no need to pee on anything, you just roll over in the morning and temp, pick up your phone and plug in the number. I was so hesitant as I thought it would stress me out but it actually put my mind at ease seeing the clear patterns.

The only way to confirm ovulation is with temping. like jny1179  mentioned, OPK’s only indicate that your body is gearing up to ovulate, but don’t actually confirm ovulation. Using CM and temping gives you a much clearer picture of what your body is doing, and should you become pregnant, it will be easier to determine an accurate due date based on when you actuall ovulated.

For thermometers, you need a basal thermometer. Most digital thermometers will provide you with accurate numbers (you want readings to the .00).

bkrocks13:  I do both, but while my temp and CM tend to indicate when I have ovulated, I don’t usually get a postive OPK. According to TCOYF, not all women have hormone levels high enough to register on an OPK – unfortunately, I seem to be one of them who doesn’t. So my temperature and CM are my most reliable symptoms.

Most digital thermometers will work, but I got a basal one for the same price at the drugstore. Temping is really easy once you get into the swing of it.

I’m in prepping to TTC mode with known infertility issues, so I can answer from that perspective. Since we know we have MFI, I want to absolutely confirm that I am ovulating. OPKs will tell me that my body is preparing to ovulate, but can’t confirm that it actually happens. I have to know that I am/am not ovulating in order for us to select the best course of action for addressing our infertility issue.

Hopefully you will never run into an infertility issue. But if you do, it’s vital information to have.

Just like LadyBear: I seem to have low hormone levels. I used OPKs for three cycles and never got a positive result: THAT was stressful! However, I had temped for longer than that and the temperature curves did indicate that I was ovulating, so that provided some relief (that and getting that BFP!). If I were you I would start out with temping (and checking CM if you feel like it, I was never that religious with that) and then perhaps complement with OPKs down the road.

bkrocks13: I’m so sorry. Sending hugs and hope your way.

We were supposed to meet with a specialist next week, but then something came up for Mr. LK at work, so we had to re-schedule. Luckily they had something open for us the next week, so it’s only a minor setback. Our nurse told us to come prepared for a lot of questions from the doc, bring my chart with me, etc. They want as much information as possible in order to lay out all of our options and the odds for each. It’s a lot to mentally and emotionally process, but at least we’re moving forward.

I chart CM because i want to know not only when i ovulate but also how my whole cycles look, whether they are normal, if problems are clearing up, Etc. We also use the same charting to avoid, so we need a little more detail than opks.

bkrocks13:  well for me I couldnt find any OPK’s that werent digital and 50-60 bucks a box for ONE cycle (20 strips to pee on and you stick it in the digital wand for a smiley face or a NO lol). Im in a major city in a booming province….. which is very odd to not to have any other options (that I saw) and having to order stuff online to canada just seemed like a P.I.T.A. I actually bought one of the 60 dollar kits and ended up as garbage because I apparently started to use it on the wrong CD :s

You need to use a basal thermometer not just a regular….its a specific family planning one just on the shelf at the drugstore (because its to 2 decimal places) It may be in the family planning section as opposed to where the regular ones are just FYI. Your temp fluctuates sometimes on a small scale and you need that extra decimal place to really get your shift because some peoples shift is only like within a degree….

Its super easy. I was feeling like it would be overwhelming but in reality you just roll over and before you do ANYTHING like dont even get up to  pee…. just take your temp when your alarm goes off….plug it into your phone fertility friend app done it creates the cahrt for you! You do need to make sure its around the same time each day because if you take it 3 hours later then your body will more the likely be diff. (I had a hard time shifting from weekdays to weekends because I do sleep in of course but I just set my alarm and then rolled over and went to sleep again!

I will tell you from experience I bought a “regular” non basal therm at first because the store didnt have a basal in stock and it definatly didnt work right. The thermometer itself was giving me diff readings even when I took it 3 times literally in a row! I used it for a week during my “practice month” before actually TTC and then got the basal (it was basically the same price) and what a huge difference on the chart holy moly!

So for example (just a very quick easy visual (literally take 2 minutes if that): if you have a piece of paper on you draw a line down the left side vertical and across the bottom horizontal. Going down the side label it from top to bottom 93.1, in the middle 93.05, and close to the bottom 93.0. Across the bottom label 1-7 spaced out a bit. (say 7 days)

If you have a regular therm and you get 93.0 for 3 days straight then 93.1 then 93.0 again then 93.1 and you stay there….all your gonna have is 2 bumps on your chart. Put a little circle on day 1-3 at 93.0…… then day 4 at 93.1….day 5 at 93.0, then day 6-7 at 93.1, now connect the dots and what do you have? a straight line with a couple of bumps that make no sense right? lol This is because the regular will round up or down to the nearest number if its more/less the .05

With the basal you could have something like this for 3 days (which would give you the 93.0 reading) Day 1-3 is 93.02, 93.03, 93.01…… then shoot up to 93.08 on day 4 (to give you the 93.1), then a slight drop to 93.04 on day 5 (which is in the middle but the regular will round it down to 93.0)…. then you go up slightly again to 93.06, and hold around 93.07 day 6 & 7……with a diff colour pen/pencil put circles around roughly where these numbers are and connect the dots you have a much better visual of whats going on! Chances are it looks like you Ov on day 4 and since your temp is now staying fairly high, its also a good indication….

I hope that made sense lol…. I know its a bit wordy but it will only take a minute to draw out just to give you an idea of the diff in thermometers

bkrocks13:  LOL re: shan’s post. I use Fertility Friend, it’s super easy and they have all kinds of articles and tutorials that are very helpful. But really you just take your temp at the same time very day and plug that value into the chart online (they have an app for your phone too). I use a basal body temp thermometer which gives the extra decimal values. I’m sorry you are struggling, it took us 18 cycles to conceive with 2 miscarriages mixed in there. I found charting very helpful.

bkrocks13:  LOL, ya out loud it sounds daunting. I used fertility friend and just had the basic version, its free (some people pay for VIP status and it gives you all kinds of bells and whistles), but all I wanted was the chart (wasnt into tracking all the other crazy stuff you apparently can) You can still enter tons of things like CM and when you BD so thats all I figured I needed. Charting is basically 60 seconds outta your day. Mornings = take temp, open the app and plug it in, and snooze for 10 more minutes haha!

But basically the point of the previous post is the importance of the right therm because regular has one decimal place and you could actually be fluctuating like crazy and have NO idea because it just rounds it off to the nearest…. some people’s temp change is only within a degree or so…..in that case then its not really gonna work very well. When people post their charts asking for help its pretty easy to see who isnt using a basal 😉

Apparently it worked for me cause I got pg the first cycle after I got my shyte together lol. Currently almost 11w!
